I have a 3 inch sulcata tortoise in a closed up tub that's big enough for him now but I feel like he's need a bigger one.does anyone know more or less how much space your supposed to give a sulcata from when he's a baby to a full grown adult? I understand the more space the better, I'm just asking is there like a guideline for space that's comfortable for tortoises of certain sizes? Just so I can have an idea of what to do as far as space goes for my growing tortoise, indoor space and outdoor.
